Bitcoin core wallet

Hello, I'm hoping someone can help me with an issue I'm having with my bitcoin core wallet. I have an offline laptop running ubuntu with core installed as the signing device. I also have another computer online running core and sparrow wallet as a coordinator. I copied an Xpub from the offline machine into sparrow and everything looks good. When I create a transaction in sparrow and try to sign it on the offline machine I get an error message. "failed to sign. Specified sighash value does not match value stored in psbt". The Xpub I copied was the m/84 and sighash on sparrow is default setting.
